Vertical Cooling buffer ( FIFO,LIFO,BY-PASS)


This vertical buffer is designed to have the function as FIFO/ LIFO and by-pass functions, which can be located between SMT machines to improve the working efficiency by buffering.This system is with the built-in magazine which has the special driving ability in each slot to transfer the boards to downstream system when the boards are called for. ( Built-in magazine is not exchangeable).

This vertical buffer is equipped with the cooling fans, and the PCB staying time in the buffer rack are available to set up for cooling length. It means even PCBs must reach the cooling time, and then when the downstream machine ask for PCB, the buffer will release the PCB .
